DRIVING MECHANISM FOR YARN MOISTENEBJS.

Application filed 'OctoberS, 1925. Serial No. 61,265.

In yarn-winding mechanism the yarns require moisture, some yarns requiring a comparatively slight degree of moisture and gree. It is consequently highly desirable that the winding mechanism be provided with means whereby the amount ofmo1s-.

ture taken up by the and easily regulated.

The object of my invention is to provide yarn-winding machine with means whereby the yarn moistening mechanism may be quickly and easily adjusted to provide for substantial or minute increase or decrease yarns may be quickly in the amount of moisture taken up by the yarns.

' which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is an end view of a coning machine equipped with my invention, c

Figure 2 a fragmentary top plan view of the same,

Figure 3 a transverse section on line 33 of Figure 1,

Figure 4: a fragmentary front view of the machine, and

Figure 5 a detail of one of the elements employed.

Referring to the drawings, 1 indicates the drive shaft of a coning machine, cam wheel fixed to the shaft, 3 a gear wheel fixed to the drive shaft, 4: agear wheelmounted upon a shaft 5 and providedwith an eccentric pin 6, 7 a link pi-voted'atonef end to the eccentric pin anda-t the other V "shaft 16, the extent of this step by step roend to a crankarm 8 fixed to a rock shaft 9. 10 is an arm adjustably secured to the rock shaft and provided with holes 11 in one of which one end of a link 12 is pivotally secured, the other end of the link being ratchet wheel 22 is fixed to shaft 16 and is This object, and otheradvantageous ends,

adapted to be actuated by a ratchet pawl posed in thepath of the. yarn and shown as of, fluted and tapered form; A trough 33 adapted to contain the moistening liquid is mounted longitudinally of the frame in such position that a part of shaft 16, or the yarn engaging element thereon, or both,- will be immersed in the moistening liquid. 27 indicates the spindle from which the yarn is led and 28 the cone upon which it is wound. T have illustrated but one yarn 7 engaging element but in practice shaft 16 will carry a series of such elements including one for eachcone.

I have illustrated at 29 tension mechanism, which may be of the usual type, and 7 I have shown the usual trip arm 30 extend ing from rock shaft 9 adapted to actuate mechanism, indicated in part at 81, 32, for throwing the cone out of commission in case of breakage of thread. These form no part of the present invention and are shown only to make clear the location of parts with reference to coning machines of the usual type.

In'operation, the yarn is led from spindie 27 through tension device 29, over the yarn engaging element 26 to the cone 28. Rock shaft 9-aeting through arm 10 and link 12 impartsa rocking movement to guide arm 15. The upward throw of the guide arm acting through pawl 23 actuatcs ratchet wheel 22 and imparts a partial rotation to tary movement, and consequently the extent of the moistened area of the yarn. engaging elements, which are brought into contact with the yarn depending upon the extent of the throw-of guide arm 15. The extent of this throw may be regulated in two ways, first by adjusting the position of the lower end of link 12 relatively to arm 10, either by means of the series of adjusting holes 11 in arm 10 or by partially rotating the arm 10 on the rock shaft 9 and clamping it in a new position, and second by adjusting the position of bolt-nut 14 in guide arm 15 by meansof threaded rod 17 which adjusts the position of the upper end of link 12 relatively to the rocking guide arm. The first affords an adjustment which, though not extensive in fact, is broad compared with that effected by the threaded rod. By making ratchet wheel 22 with a multiplicity of teeth and making the pitch of the thread on rod 18 fine, I provide for any required nicety of adjustment. 7

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am liberty to make such changes and alterations as fairly come within the scope of the appended claims. Having thus described-my invention, What I claim as new and desire to secure by Let-, ters Patent is V 1. In a yarn Winding machine having a rock shaft; a liquid carrying trough disposed adjacent the path of the yarn; a moistening roller extending into the liquid in the a trough and secured to a, rotatable shaft; a

ratchet wheel fixed to the rotatable shaft;

a guide arm loosely mounted on the rotatable shaft and carrying a pawl adapted to actuate the ratchet wheel; a rock arm secured to the of the ratchet wheel movement, and means on the guide arm for making fine adjust-:

ments of the ratchet wheel movement.

2. In a yarn winding machine having a rock shaft; a liquid carrying trough disposed adjacent the path of the yarn; a tapered moistening roller extending into the liquid in the trough and secured to a rotatable shaft; a ratchet wheel fixed to the rotatable shaft; a guide arm loosely mounted on the rotatable shaft and carrying a pawl adapted to actuate the ratchet wheel; a screw adjusted slidable member mounted in the guide arm whereby fine adjustments of the ratchetwheel movement may bemade;

a linkhaving one end pivotally connected to the slidable 'member, and a rock arm secured to the rock shaft having apertures in its extending portion for connection to the other end of the link whereby coarse adjustments of the ratchet wheel movement may be made.

3. In a yarn-winding machine, a liquidcarrying trough disposed adjacent the path of the yarn; a rotatably mounted shaft, extending longitudinally of the trough, having a fluted moistening roller fixed thereto extending into the liquid and adapted to engage the yarn; a ratchet wheel fixed to the shaft; a rockable guide arm loosely mounted upon the shaft and carrying a pawl adapted to engage the ratchet wheel; a bolt-nut slidably mounted in the guide arm; athreaded rod taking through the bolt-nut and held against longitudinal movement in the guide arm; a rock shaft; a rock arm mounted on the rock shaft; a link pivotally connected withsaidrock arm and with the bolt-nut; means for changing the position of the link on the rock arm, and means for actuating the rock shaft.

4. In a yarnwinding machine, a liquidcarrying trough disposed adjacent the path of the yarn; a rotatably mounted shaft extending longitudinally of the trough, having a fluted moistening roller fixed thereto extending into the'liquid adapted to engage the yarn; a ratchet wheel fixed to the shaft; arockable guide arm loosely mountedupon the shaft and carrying a pawl adapted to engage the ratchet wheel; a bolt-nut slid--- ably mounted in the guide arm; a threaded rod taking through the bolt-nut and held against longitudinal movement in the guide arm; a rock shaft; a rock arm mounted on the rock shaft; a link pivotallyronnected with said rock armand with the bolt-nut; means for adjusting the position of'the link on the rock arm, and means for actuating the rock shaft.

In testimony whereof I have signed my 7 name to this specification.
